UPS 电源认证!
公司的一个UPS需要做UL+CB, 今天问了UL了,他们说只能做UL,不能做CB。超级郁闷中~~~
大家说下,还有这样的道理吗???
补充问题,UPS做IEC62040标准就OK了吗?
还需要其他的吗? :(学习经验了 去北美须做UL1778的标准,去欧洲做IEC/EN62040就可以了

谢谢! 了解。 M.4 Overcharge conditions ----引直IEC62040-1-2008
If a measurement is needed to determine if a battery compartment complies with Clause M.2,
the battery charger shall be connected to a supply circuit adjusted to 106 % of nominal
voltage and then subjected to 7 h of overcharging using a fully charged battery. Any
operator-adjustable controls associated with the charger or charging circuit shall be adjusted
for the most severe charging rate. 想了解下106 % of nominal voltage 这个106%标称电压是指电池充电电压还是UPS的输入电压(或充电器的输入电压)
Exception 1: This requirement does not apply to a UPS to be used with a battery charger that
is not investigated with the UPS.
Exception 2: This requirement does not apply to a UPS provided with a regulating circuit
preventing an increase in battery charging current and voltage when the a.c. input voltage is
increased from rated value to 106 % of rated value. 感謝, 讓我長知識囉 LZ,那你研究出来了没,究竟是否有这种说法?不能做CB? 经验啊,现在能加吗? UL 还是不可以直接做CB, 但是貌似其他的机构可以出CB。
